* An estimate of the number of pioneer workers needed for initial church planting among unreached people groups by country. Estimates are calculated only for unreached people groups and are based on ratio of 1 worker for every 50,000 individuals living in an unreached people group by country. Some workers may already be onsite. Many more workers are needed beyond this initial estimate.

Joshua Project data is drawn from many sources and of varying accuracy depending on source and editorial decisions. Populations are scaled to the current year. Other data may have varying ages. We welcome suggested updates.

A displayed zero can mean true zero, a very small rounded number or sometimes unknown. Blanks mean an unknown value.

The data is sometimes not as precise as it appears. Values for %Christian Adherent and %Evangelical (which determine unreached status) are often informed estimates, some more accurate than others. We recommend against using %Christian Adherent and %Evangelical for precise calculations.
